Abstract:
Snow and first-year sea ice ridge thickness, draft, and morphology were measured using a 2-inch ice drilling auger (Kovacs Enterprises) during walking surveys on the first-year ice ridge during the MOSAiC expedition. Drilling was performed during June and July 2020 across seven drilling transects. The total covered area was approximately 35 m by 25 m. The investigated “Jaridge” was formed on February 4–12, 2020 between first- and second-year ice and consisted mainly of 0.2–0.4 m thick ice blocks. The ridge was located on drifting sea ice in the Arctic Ocean within the Central Observatory of MOSAiC.
The table contains the event label (1), event ID (2), time (3), and global coordinates (4,5) of each drilling measurement. Each separate drilling hole has its number (6), and local coordinates X (7) and Y (8) in [m]. Global coordinates are given for the local coordinates of (0,0). For each drill hole, the depth relative to the waterline of the top (9) and bottom (10) interface of each separate layer is given together with its ice type (11). Ice types include snow, ice, and water. The drill hole with local coordinates of (0,0) coincides with the ice mass balance buoy 2020M26 installation described in doi:10.1594/PANGAEA.926580. The drill holes with local coordinates of (7.5,20) and (19,35) coincide with the isotope and salinity data from ice coring described in doi:10.1594/PANGAEA.943746 for events PS122/4_46-178 and PS122/4_47-199.
